1. Visualizing involves creating mental images of what is being read, which can help strengthen comprehension. Proficient readers visualize before, during, and after reading. 2. When visualizing, readers draw from their background knowledge and experiences to imagine details and develop a deeper understanding of the text. 3. Teachers can help students learn to visualize by having them describe images aloud, look at pictures related to the text, or listen to audio and sketch what they envision. Sharing visualizations can also aid comprehension.
